METHOD OF BUTTING .AND POINTING THE BUTT TO BE SAWED INTO SHINGLES.

Specification of Letters Patent No. 19,167, dated January 19, 1858.

To all 'whom t may concern Be it known that we, Mosns I). WELLS andALPI-Inns IVELLS, of Morgantown, in the county of Monongalia and Stateof Virginia, have invented a new and useful in Improvement inShingle-Machines; and we do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawing, forming part o-f thisspecification, in which- Figure l is a top view of the machine. Fig. 2is an end elevation of same. Fig. 3 is a vertical section on line fe.

Similar characters of reference in the several figures denote the samepart.

The object of our invention is the alternate elevation of the oppo-siteends of the bolt in a simple manner.

The nature of the invention consists in resting the bolt upon two sharpedged vertical slides, alternately elevated and depressed by themovement of a horizontal piece upon which they rest.

The details of construction and operation are as follows: In the drawingS is the horizontal saw, by which the shingles are cut.

C is the carriage in which the bolt. is secured by dog (Z, andreciprocated on ways a a in any suitable manner..

B B are the vertical slides having their upper edges b sharp, as shownin Fig. These slides rest upon the upper edge of the horizontal slide D,which consists of two inclined planes c c with the depression in themiddle. The cross F, G, H, of the frame act as guides to the slides B B.The

slide D is reciprocated by the rock shaft its arm h being in connectionwith the slide and power applied to arm it.

In operation the bolt rests upon the knife edges b I) of the slides;Adog (Z being removed by rotation of shaft The bolt is then dogged inthe Carriage, and the shingle cut. The carriage is then run back, andthe bolt released. The horizontal slide is then moved, elevat-ing the.lowest slide. On again securing the bolt in the carriage and running itto the saw, the butt of the shingle cut will be from the opposite end ofthe bolt from that which furnished the butt of the first shingle. Inthis manner the butts of shingles are made to come alternately fromopposite ends of the bolt.

By this construction the opposite ends of the bolt are alternatelyelevated and depressed with but the slightest expenditure of power. Thesharp edges b b cause but little friction in the passage of the boltalong them.

The several parts of the machine may be so regulated as to be operatedautomatically.

XVe make no claim to regulating the position of the bolt by anoscillating' table', but

That we do claim and desire to secure by Letters Patent is- The verticalknife edge slides B B', and horizontal double inclined slide D, incombination with each other and the carriage and saw substantially asand for the purpose set forth.

In testimony, we have hereunto signed our names before two subscribingwitnesses.
